Abstract: PURPOSE:To obtain a small-sized sensor adaptable even to a transparent liquid and capable of detecting even a small amount of a liquid and having a simple structure by utilizing a change of a total reflection critical angle generated by the presence of the liquid to be detected in contact with a reflecting surface. CONSTITUTION:One surface of a light guide member 3 is set to a reflecting surface 4 and the light of a light emitting element 2 is applied to the reflecting surface 4 and the reflected light thereof is detected by a photodetector 1. As the material quality of the light guide member 3, glass or a resin material such as polycarbonate having high light transmissivity is used. As the elements 2, 1, a light emitting diode for emitting infrared rays and a phototransistor both of which strong against disturbance and capable of obtaining sufficient quantity of light and sensitivity are used. An incident angle is set at such an angle that total reflection is generated in such a state that the reflecting surface is not in contact with a liquid to be detected but not generated in a contact state and light is allowed to irradiate so that at least a part of said light emitted from the element 2 is incident to the reflecting surface 4. When a liquid level reaches a level covering the intersecting point 5 of the reflecting surface, no total reflection is generated and, since no light reaches the element 1, the liquid level can be detected on the basis of the magnitude of the detection quantity of light of the element 1.
